Re: [Translation-i18n] Memory management in gettext?

Hi Chris,

bug-gnu-gettext is a slightly better mailing list for this type of question;
I'm adding it in CC.

No, it won't run out of space. "statically allocated" here means allocated
with indefinite extent. If you keep passing new domains to dgettext, dcgettext,
the MO files will be loaded and transformed to "statically allocated" memory.

If gettext(s) != s, you are guaranteed that gettext(s) is statically allocated,
that is, you can access it as long as you want, and it will not be discarded
from memory. Of course, if gettext(s) == s, then it depends on how the caller
has allocated s and will free s.
